Wiring Problem for Honeywell RTH9580WF1005 Smart Thermostat

I am looking to upgrade my current thermostat to this newer Honeywell Smart Thermostat. My problem is that I currently do not have a C wire at the thermostat unit. In addition, once i open the control panel at the furnace unit, i see that there is no Y wire connected to the Y terminal (But there is a Y wire at the terminal in the wall unit). Is it possible to still upgrade to the new thermostat or do i have to rewire the entire system? Its very weird how the wiring does not match from the poles at the wall unit to the furnace. i will include pictures for further explanation. any help will be appreciated.
